Precision image animation
Kling 2.1 Pro is the professional-tier configuration of the Kling 2.1 generation — focused on high-fidelity image animation with first-and-last-frame conditioning. This means you can specify both the opening and closing image of a clip, giving you deterministic control over what the video looks like at the start and end while the model handles the transition. Enhanced sharpness and advanced interpolation deliver crisp motion at every frame — a step up from the standard 2.1 tier for commercial and professional content creation.Capabilities
First-and-last-frame conditioning
Define the exact opening and closing frames — Kling 2.1 Pro generates the motion between your specified images for precise transition control.
Enhanced sharpness
Improved rendering for fine detail, realistic lighting, and surface clarity versus the standard 2.1 tier.
Advanced interpolation
Crisp, detailed motion between frames — no blurry or artifact-heavy transitions in fast-moving sequences.
Professional visual fidelity
1080p output with color accuracy and visual consistency suitable for commercial, advertising, and content production.
Image-to-video workflow
Animate any reference image with natural motion, accurate lighting continuity, and subject consistency.
Text-to-video
Generates directly from text prompts with strong prompt adherence for scene composition, subject behavior, and camera style.

How to use
- Image to video

Add a last frame (optional)
Upload a second image to use as the ending frame for a controlled transition.
Describe the motion
Write a prompt describing how the scene should move — camera behavior, subject action, atmosphere.
Prompting tips
- For first-and-last-frame: let the images do the visual work — Your prompt should focus on motion style, pacing, and atmosphere rather than describing what’s visible in the frames.
- Specify motion timing — “Slowly” vs “quickly” significantly changes the feel. “The character turns in 2 seconds with a graceful, measured movement” is more useful than just “the character turns.”
- Use lighting continuity — If your reference image has specific lighting, describe it in the prompt so the model maintains consistency through the motion.
Example prompts
A luxury watch sits on a velvet surface. The camera slowly orbits around it, revealing the face and side profile. Soft studio lighting, no harsh shadows. 8 seconds.
A cityscape transitions from dusk to night. Time-lapse style, lights flickering on across the skyline, smooth motion. 10 seconds, 16:9.
